A restaurant in Chelsea, London, has created the world's most expensive burger at £1,100 (around $1,769), with contents as exotic as gold leaf, lobster and caviar. The world's most expensive burger took three weeks to be developed by the restaurant's chefs, and each of its 14 ingredients is reported to cost an average of £78.50.

The restaurant that created the world's most expensive burger, Honky Tonk, is located in the Chelsea neighborhood of West London and is themed as an American diner-style joint. The cooks in the now-famous restaurant had set out to make a ridiculously high-priced burger, and they certainly managed to do so in this piece that took three weeks of crafts making in the Chelsea kitchen.

According to United Kingdom journal The Independent, the burger's patty consists of 220g of Kobe wagyu beef, minced with 60g of New Zealand venison. At the center of the meat, consumers will find a black truffle Brie - all seasoned with Himalayan salt, with Canadian lobster poached in Iranian saffron. In other words, the world's most expensive burger features at least five different nationalities in its patty alone.

There's actually more meat in the mix - and yes, that's possible -, as chefs also added bacon (with a maple syrup coating), beluga caviar and a hickory smoked duck egg covered in gold leaf. Certainly, if there's one thing you can say about the world's most expensive burger it's that it certainly features protein - though perhaps much more than the body should consume in one sitting. Indeed, the entire burger has 2,618 calories, a number that exceeds the recommended daily intake for an adult.

The world's most expensive burger was actually created as a publicity stunt for the Chelsea restaurant in partnership with Groupon, and it will be the prize in an upcoming contest.

It's not the first time in the past few days that the United Kingdom makes news for exaggeratedly expensive meals - recently, a new bar introduced the world's most expensive cocktail in Mayfair, also in London.
